This is ANI II data, and SIP does not support it in a standard way
(SIP-T does).  You can sometimes get this delivered as either an extra
SIP header (X-ANIII for example) or via isdn pri lines.
You may be able to get the info you need from LIDB.  Its normally not
free, its normally per query, and often its SS7 although there are
standards for getting it via LDAP and other methods.
